There isn't a cavity or any insulation at the minute no just single skin.
Ah okay, trouble is I don't want to reduce the size inside to much so it was seeing what I could get away with.
Are we saying celotex is a better way forward than insulated plasterboard though?
Hi all,
I'm looking to convert my new garage intk additional room used for working in.
It's single skin detached with a pitched roof newly built (if that makes a difference).
Obviously I want to make this into a normal room adequately insulated and holds of the mould that seems to appear after...
